HOBBLE r011 MOTOR-VEHICLES.

Specification of Letters Patent.

Patented May 27, 1919.

Application filed February 9, 1918. Serial No. 216,291. I

To all whom it may concern:

Be it known that we, JOHN J. MODADE and FRANK P. DoNNELLY, citizens of the United States, and residents of Dorchester, in the cbunty of Suffolk andState of Massachusetts, have invented certain new and useful Improvements in Hobbles for Motor- Vehicles, of which the following is a specification.

Our invention is an improvement in hobbles for motor vehicles, and has for its object to provide adevice of the character.

specified adapted to be looked upon the wheel of a motor vehicle, to lift the wheel once during, each rotation thereof, to impart an uneven or hobbling motion to the vehicle, to add an unwonted or unusual condition in the vehicle, to call attention to the same.

In the drawings:

Figure 1 is a side View of a motor vehicle wheel, with the improvement in place;

Fig. 2 is a perspective view of the hobble;

Fig. 3 is a vertical section through the hasp;

The present embodiment of the invention is shown in connection with the wheel 1 of a motor vehicle, and the improvement comprises a bobble consisting of an are shaped plate 2, which is of considerable thickness at its center, as shown more particularly in Fig. 2, gradually decreasing in thickness toward its ends, and at each end the plate has an extension 3 and 4, respectively.

The-extension 3, as shown, is integral with the plate, while theextension 4 is hinged to the plate as indicated at 5 in order to swing toward and from the extension 3. This extension also hasa staple 6 on its outer face, the staple having the usual opening for receiving the shackle of a paddock -7.

A flexible member, as, for instance, a chain 8, is connected with the extension 3, and this chain is of a length to pass around the folly when the plate 2 is engaged with the tire of the wheel, the convexity of the tire resting in'the concavity of the. plate.

A hasp plate 8 is connected with that end of the chain remote from the extension 3, and this hasp plate, as shown, has a series of transverse slots 9, which are ada ted to be engaged by the staple, to permit t e passage of the staple through the hasp plate. At the end of the hasp plate remote from the chain there is a hook or finger-piece 10 for convenience in engaging and disengaging the hasp plate.

In use, when the driver is to leave the vehicle, for any length of time, the hobble is placed, being arranged on that portion of the tire which is not in engagement with the ground. The plate is placed as shown in 2, and the chain is passed about the e y: ple 6, after which the lock is applied.

Should, now, unauthorized parties start the vehicle, limping or hobbling motion, which will be unusual, and will attract attention, since the Wheel and the vehicle will be lifted every time the bobble plate 2 passes beneath the wheel.

It will be evident that the hobble may be applied to any of the wheels, since its efieot Will be practically the same wherever applied.

We claim:

the hasp being engaged with the stathere will be imparted to the same a A hobble for motor vehicles comprising a 1 plate formed arcuate for conforming engagement upon the tread of a tire and adapted to raise the wheel from the ground. during each rotation thereof to impart a limping movement to the vehicle, an ear hingedly connected with one side edge of said plate, a

lug formed on said ear and extending outpadlock.
